Answer:
They are
4+6=10
200/10=20
ratio4= 20x4 = 80
ratio6= 20x6= 120
to prove it do 120+80= 200
The first option is a function as it passes the vertical line test and as each domain (x value) is paired with exactly one range (y value)
Since the problem said he uses 160 feet of fence, you know that is the perimeter
P = 2l + 2w
You know that one of the dimensions is 50, so you can plug that into the equation
160 = 2 x 50 + 2w
160 = 100 + 2w
2w = 60
w = 30
The area is equal to l x w
50 x 30 = 1500 square feet
Perimeter: x + (4x + 9) + (x + 11)
The value x is for the bottom of the triangle.
Simplified, it would be 6x + 20
